WINDOW-REGULATOR-HANDLE ASSEMBLY.

Application filed October 9, 1922. Serial No. 593,166.

- This invention relates to a Window regulator handle assembly. It has for its ob1ect an improven'lent. in the mounting of the handle upon the escutcheon plate and an improve-- ment in the attachmentof the escutcheon plate to the regulator casing. 5 V

Herctofore there have been several ways of mounting the regulator handle on the operating shaft. The first way and possibly the most obvious way, was to simply square the'end of the operating shaft and pass the hub of the crank handle over the shaft and secure it in place by a set screw. This was, however, found to be crude and unsatisfactory.

Another way that has been quite extensively used'and quite satisfactory, has been to attach the handle to the operating shaft by a split nut and groove assembly such as shown and claimed in the Allmand Patent No. 1,278,552. This escutcheon plate in no way supports the handle, hence was not a bearing plate but simply a finishing plate to 'cover up the rough ends of the trimming.

- This plate was simply held loosely between the nut and the trimming.

, A third common way of mounting the handle has been to secure the escutcheon plate and hub of the handle together so that the handle can rotate in the-escutcheon plate but cannotbe uncoupled therefrom. In order to couple the handle up with the operatingshaft, it is then necessary to secure the escutcheon plate to the cover plate of the regulator by means of a plurality of screws. These screws have their heads exposed and consequently mar the appearance of the internal fittings of the car.

It is the object of the present invention to provide an escutcheon plate which is alsoa bearing plate in which the handle is rotatablysupp'orted and" at the same time afford an attachment between the escutcheon plate and the regulator casing which isentirely concealed and wholly eliminates the screws.

In the drawings: Fig. 1 is an elevation of the window regulator showing the pressed metal cover plate in position. I

Fig. 6 is an-elevation of the inside of a closed car showing the escutcheon plate.

Fig. 7 is an enlarged elevation of the same.

The regulator parts will be apparent from. an inspection of the drawing; no claimis made to any particular form of regulator. The regulator here shown-has a chain lift, the chain being designateda; on this is a lifting .pin 1) which connects with the window in a familiar way so that the window rises and falls with the movement of the chain. The chain runs over a lower sprocket wheel (I and an upper sprocket wheel e. The sprocket wheel-is driven through the gears f g and h. The driving pinion his driven through a clutch contained in the housing 2' and which need not be detailed here as the same is no part of the invention. The operating parts are enclosed by a pressed metal coverplate j which is secured to the main supporting plate is by the screws m.

A ferrule n either internally screw threaded as shown in Fig. 3, or-provided with the equivalent construction, a bayonet slot as shown in Figs. 4.- and 5, is used. The cover plate is provided with a ring boss 0 and a punched hole p with key lugs g punched out. The ferrule is provided with key slots 1' adapted to fit over these key lugs to prevent the ferrule from turning. The bottom of the ferrule is provided with a ring boss s which fits into the perforation punched in the cover plate. The flanged brass bushing 25 is then fitted into the ferrule as shown in Fig. 2 and the outer end riveted over as at u. This securely locks the ferrule to the cover plate and constitutes, in a broad sense, an anchor that fits over the squared end 2 of the operating shaftwhich connects with the clutch contained in the case This escutcheon or bearing plate may be united orlocked on to the hub of the crank handle so thatthe hub can rotate therein in several ways. The end the bayonet joint parts .or screw threads on .claims.

the inside of the ferrule thetrimming material will not get into the threads or be torn thereby.

The main supporting plate of the regu lator is secured to the lock board in a fami1- iar way. The trimming for the door or body is then secured over the lock board and the regulator cover, exposing only the ferrule. Only a small hole is necessary to permit the ferrule to protrude through the trimming,

no allowance has to be made to permit screwsor other fastening device to pass through the trimming material. The handle may then be very easily mounted on to the door or connected with the regulator by simply screwing the escutcheon or bearing plate into the ferrule. This may be done with the fingers;

as the plate is screwed down it will press into the soft trimming material whichwill constitute a very good lock nut to lock the plate in place.

In the claims I have referred to the threads and the bayonet joint generically as parts of locking devices which detachably engage.
